NVIDIA and OBS team up to reduce the hardware burden of live streaming

Live streaming is one of the most demanding tasks you can place on your PC, but NVIDIA and OBS hope to make it easier. For a measure of just how taxing it is, you only need to look to the fact that many serious streamers rely on a second PC dedicated to live streaming to avoid performance drops in game. 

Having said that, the new version of OBS now comes with built-in optimizations to help people who use NVIDIA GPUs stream from just a single PC. The improvements are made possible via the NVENC hardware encoder used by NVIDIA GPUs, and NVIDIA says OBS Studio version 23 can reduce the performance hit on your FPS by up to 66 per cent, compared to the previous version.

The good news is that you won't need NVIDIA's new Turing GPUs to take advantage of this, and it will work with GPUs from the GeForce GTX 600-series and newer. However, the Turing cards do offer slightly better encoding efficiency – they are up to 15 per cent more efficient – which means you can achieve the same quality with a lower bit rate. This is particularly useful if you don't have a super fast internet connection, where you'll be able to lower your bit rate without compromising on image quality too much. 

According to NVIDIA, the new optimizations can improve frame rates by up to 48 per cent in Fortnite, PUBG, Call of Duty: Black Ops 4 - Blackout, and Apex Legends, when compared to x264 Fast encoding. It's not coincidence that NVIDIA has singled out these battle royale titles for special mention, considering how they're currently dominating the Twitch charts. 

OBS Studio version 23 is now available for download for both Windows and macOS. That's not all though, and NVIDIA says that StreamLabs, another popular broadcasting software, will also implement these same optimizations in the near future. If you're looking for a guide on how to configure your stream, NVIDIA has also released one here.
